The Senate, on Wednesday, rejected a bill by President, Muhammadu Buhari seeking the amendment of Section 84 (12) of the Electoral Act.
Section 84 (12) prevents political office holders from contesting for election from the party primary level without resigning.
The bill had scaled the first reading on Tuesday, despite a court order barring the Senate from acting on it.
The request was rejected after Senator Yahaya Abdullahi made the lead debate for the second reading of the bill on Wednesday.
The Senators kicked against it and voted no when put to voice votes by the President of the Senate, Ahmad Lawan.
